'IO WHOM IT MAY CONGERN: Y u e Be it known that I, Lonen B. Fons'TER, ofC1yde,in the county of St. Clair, and State of Michigan, have invented anew and useful Improvement in Self-Packing .Pipe and Hose-Coupling and Ido declare that the following is a true and accurate descriptionthereof, reference being had to the accompanying. drawings, and to theletters of reference marked thereon, andbeingapart of thisspecification.

Figure lisa perspective view of my invention in operatioh. i

Figure 2 is a-perspective vie'w ofthe same disconnected.

Figure 3 is'a sectionalview ofthe same, showing the packing, andoperation of the levers."

The same lettersin-dicate like `parts in each figure;

The natureof thisinvention consstsjn attaching a coupling, for joiningtivo ends of pipe or hose together, that will be perfectly tight, andinstantly'disconnected when required; that will resist any reasonablestrain, and whosefpacking will always bein order. u u

lIn order to accomplish this end, I rigidly fasten to the pipe A, ashort and larger pipe, B, which leaves an annular space around the innerpipe A, which space is provided with suitable packing, C, of rubber, orother l proper'material. The outer pipe,`B, is provided with suitableears, l), to which are provided the dog-levers E, which are furnishedwith shoulders F,'for the purposes hereinafter described. To the pipeGis also rigidly attached the conpling-pipe H, provided with a shoulder,I. This pipe H should accurately fit the outside cirvcumference of thepipes A and G, tu the latter of which it'is fastened. Upon the pipe Hisloosely sleeved the ring J, and is held in place hyapropenpin, K, whichis attached to the pipe H, and workin a suitable slot,L, the ring J.Thespiral spring M, obtaining resistance by being attached to the pipeH,'is designed to compel the ring J' to engage with the catches N uponthe ends/of the dog-levers E, and hold the same in position', as shownin Eg. 1. V l

To couple ytwo pieces of pipe or hose, provided with my apparatus, thedog-levers-E beingthrown back, as in iig. 2, enter the coupling-pipe Hinto the `pipe B, and round the pipe A, until the shoulder I comes intocontact with4 the packing C. Then swing the dog-lerers E into a parallelposition relative to the coupling-pipe H, and slip the ring J over thecatches N, where it is heldin position by the spring M. To uncouple,slip the ring J back, freeing the catches N, when the shoulders F, whichare engaged with .the shoulder I, will be disl engaged, and the variouslengths of pipe or hose removed. l What I desire to secure byvLettersPatent, as my invention, is-

The pipe B, attached to and Vsurrounding the pipe A, Vthe packing C, theears D, the dog-levers E, pro-l vided with shoulders F, and catches N,to form' that part of my coupling attached to the pipe A, when operatingsubstantially as and forthe purposes herein described. i Also thecoupling-pipe H, provided with lshoulder I, ring I, pin K, slot Ir,spring M, in connection with pipe G, when constructed and operating toforni the otherpart of my coupling.

Also the combination and arrangement of all the above-named parts toform the two parts of a coupling,

whenconstructed and operating substantially asand for the purposesherein set forth.
